Indoor air testing has three big trap a scene out of the test results many domestic indoor air testing company, but some is not the result of Quality Supervision Bureau certification, consumers in the choice of the detection unit must pay attention, do not be fooled. No certification qualified testing agency after the indoor testing, site of the test results, it turns out, most of this detection method is void. The correct air testing is done in the laboratory, formaldehyde and ammonia by spectrophotometer, TVOC and BTEX is detected by gas chromatography. Second, in order to take advantage of free testing bait free indoor pollution detection bait. Some management companies use some consumers want to spend more afraid of the indoor environment testing of psychology, free indoor environment testing as bait, then high indoor environmental pollution control, these companies earn a lot of money management is the late fee. Third, the false indoor pollution levels are also some testing organizations, will exaggerate the test results in addition to formaldehyde product sales, false indoor pollution degree to make indoor pollution control business.

Decoration pollution includes five items: formaldehyde, benzene and BTEX (toluene, xylene), radon, ammonia and TVOC. Mainly because of plywood, paints, adhesives, wallpaper, carpets and other decorating materials caused by the release of these toxic gases exceeded. Once the existence of decoration pollution, volatile period will last up to 1-5 years. 1, formaldehyde. Strong irritant gas Formaldehyde is a colorless addition of formaldehyde products, mainly from the interior of plywood, block board, medium density fiberboard and particleboard and other man-made plates, the use of artificial system board crafted furniture, components containing formaldehyde and possibly to other kinds of decorative materials distributed outside world, such as stickers wall coverings, wallpaper paste, synthetic carpets, foams, paints and coatings. 2, benzene and BTEX. Benzene is a colorless gas with a special aroma, benzene mainly from glues, paints, coatings and adhesives. 3, radon. Radon (222Rn) is a radioactive gas, and its decay daughter products is a solid addition to formaldehyde cooperation, and therefore also produce radon inhalable particles of radioactive substances. Radon In nature there are three kinds of radioisotopes exist, the parent element radon is uranium, which can be dissolved in water and a lot of liquid, but also dissolves in the blood and fat. The main source of radon: cement and other building materials, stone, tile, water and fuel (coal, gas, etc.). 4, ammonia. Ammonia is a colorless and has a strong pungent odor of gas is lighter than air (specific gravity 0.5), ammonia is an alkaline substance, high solubility. Ammonia mainly from concrete antifreeze, toilet odor, etc. used in building construction.
